When buying tires, there are some key points that you have to consider. And before you even decide, you have to understand the basics, including the sizes, the specifications, and the uses or applications. It is important for you to know and understand these things because you need to be aware of your tire’s technical capabilities. Let’s start with the code first. Tires have a code molded into their sidewall, which provides information on the size, construction, speed rating, and capacity for carrying a load.
Here is an example of tire specifications:
205/65R15 95H
205 – This is the width or the measure of the actual section of the tire in millimeters.
65 – This number refers to the tire’s aspect ratio or the dimensional relationship of its height to its section width.
15 – This indicates the actual diameter of the wheel rim.
R – This refers to the radial ply construction.
95H – This indicates the maximum load capacity of the tire and the ideal speed at which it can be safely used, considering that it is in good condition, is properly and accurately fitted, and has the recommended inflation pressures.
What are the general functions of tires for all types of vehicles?
Weight-bearing
In order to carry and maintain the weight of the vehicle, the air pressure and tire construction should be considered as very important factors.
Shock-absorbing
The air pressure and tire construction decrease the road vibrations and shocks before they get subdued by the suspension.
Delivering power from the engine
Tires are the ones that deliver the power from the engine of the vehicle for it to move. It is also the tires that provide traction and braking ability.
Translating steering wheel movement
The tires are important in keeping the vehicle’s stability in driving. They are also important in controlling the direction of the vehicle.
Other considerations when it comes to tires
Upsizing
Upsizing is an option being considered by vehicle owners who want to customize their vehicles, and they get it done by installing lower aspect ratio tires on wider and larger diameter rims. If you are deciding whether to upsize, here are some important aspects that you need to consider:
Load Capacity
– The load capacity should equal or exceed the original equipment tire fitment.
Inflation pressure
– You must remember that you should never use a tire inflation that is lower than the OEM’s recommendations. It is important to sustain the pressure relationship between the front and the rear axle tires.
Speed rating
– The speed rating should either be equal to or greater than the original equipment tire fitment.
Rolling circumference
– The original equipment rolling circumference should be monitored and maintained as closely as possible.
Tire and rim combination
– Using the tire size and rim approved by the industry is recommended.
Body and chassis clearance
– Ensuring body and chassis clearance under all service conditions is important.
Balancing your tires
Every time a tire is replaced, snap-in valves must also be replaced. In order to avoid contamination of the valve core and air loss, it is important to fit appropriate valve caps. Wheels must be balanced, or they will produce an uncomfortable vibration to drive in. This is why a tire must be correctly balanced to reduce or eliminate vibration and avoid unnecessary wear.
Use appropriate tires for specific seasons
It is highly recommended to use the appropriate tires for each specific season, and this means you should use summer tires when it is warmer and use winter tires when it is the cold season. This way, you will be able to maximize all aspects under all weather conditions and achieve optimal performance of your tires. When you use the appropriate tires, you can be guaranteed of a good grip on the road, even when it is wet or dry.
